Lateboater, the name gives you the clue.

The Rootes outboards were U.S Oliver designs produced in the U.K by Perkins, Rootes and finally died under British Anzani ownership.

No where near as bad an engine as people claim.

Rootes Group. The Rootes Group did own Tilling Stevens down in Kent which produced the TS3 diesel engine for Commer trucks, which was also part of the Rootes Group.

In order to find additional engine volume Rootes entered into an agreement to allow Lister to marinise the TS3 and market the engine as the Roots Lister TS3.

However I digress, a nice piece of boating memorabilia, all parts common with equivalent Perkins and Anzani motors. Also Oliver if you can source them.
